Concerning Sin, Righteousness, and Judgment(English Edition) [EPUB ebook] 

Today, there are many people who go on with their lives not even knowing what sin is, what righteousness is, and what judgment is all about. Even those who go to church don’t have assurance of salvation, and they live secular lives-just like everyone else in the world. Furthermore, they do not lead Christian lives that are righteous according to God, but righteous according to what they think is righteous. So Concerning Sin, Righteousness, and Judgment is the first book of the Holiness and Power sermon series which deals with how we can lead a successful Christian life by receiving forgiveness for our sins and by accomplishing the righteousness of God in our lives.
